Cubase 11.0.40 issue export audio 5.1

Hi everyone, I did the update from cubase pro 11.0.30 which works great, to 11.0.40.
The very serious problem is that when I export 5.1 audio, the operation starts and then Cubase freezes completely.
I need to use the task manager and restart cubase. It is practically impossible to work with it. And to think that they have improved the audio export …
I am now back to release 11.0.30
After the 10 pro release it became a risk to upgrade cubase. I can’t understand how you can make these colossal mistakes that naturally for those like me who use them professionally this creates many problems.
Hope they will solve it soon.

Hi and welcome to the forum,

I expect you are on Windows. Once Cubase freeze, could you make a DMP file from the Task manager, please?

Then share it via Dropbox or similar service, please.
